Used law of superposition and applied it to. rock strata. Vertical and horizontal layers observed. Vertical layers deposited first horizontally but were. then tilted. Horizontal layers deposited after a period of erosion. Top surface of the lower vertical layers is called an. unconformity (a surface in a rock sequence that. represents a break in the pattern due to erosion or. a lack of deposition)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
